The present invention relates to pyrazolo[1,5-a][1,3,5]triazine derivatives and/or pharmaceutically acceptable salts thereof, the use of these derivatives as pharmaceutically active agents, especially for the prophylaxis and/or treatment of cell proliferative diseases, inflammatory and immunological diseases, cardiovascular diseases and infectious diseases. Furthermore, the present invention is directed towards pharmaceutical composition containing at least one of the pyrazolo[1,5-a][1,3,5]triazine derivatives and/or pharmaceutically acceptable salts thereof.

Cyclin-dependent kinase (CDK) family members that trigger passage through the cell cycle are being considered as attractive therapeutic targets, especially for cancer. CDK family members that control other processes such as transcription and RNA processing have caught less attention so far, although experimental evidence for their involvement in different pathological processes is emerging. The CDK-activating kinase, or CAK complex, consists of CDK7, cyclin H, and MAT1. As part of CAK, CDK7 phosphorylates other CDKs, an essential step for their activation. Therefore CDK7 is required for cell cycle progression, which suggests that CDK7 is a target for cancer therapy. As the kinase subunit of TFIIH, CDK7 participates in basal transcription by phosphorylating the carboxy-terminal domain of the largest subunit of RNA polymerase II. As a general regulator of transcription, CDK7 is a therapeutic target for treatment of diseases like inflammation, virus replication such as HIV, EBV, and HCV, cancer and cardiac hypertrophy.

HIV-1 gene expression is regulated by a viral transactivator protein (Tat) which induces transcriptional elongation of HIV-1 long tandem repeat. This induction requires hyperphosphorylation of the C-terminal domain repeats of RNA polymerase II. To achieve said hyperphosphorylation, Tat stimulates CTD kinases associated with general transcription factors of the promoter complex, specifically TFIIH-associated CDK7. (Nekhai et al.; Biochem. J. (2002) 364, 649-657). Also the inventors of U.S. Pat. No. 615,968 describe that Tat binds to CDK7 and that this interaction increases the ability of CAK to phosphorylate CTD. The authors of U.S. Pat. No. 615,968 further disclose that the transcriptional activation by Tat is dependent upon the kinase activity of CDK07. Additionally, Young Kyeung Kim and colleagues conclude that the recruitment and activation of TFIIH represents a rate-limiting step for the emergence of HIV from latency (Young Kyeung Kim, EMBO I (2006) 25, 3596-3604).

Levels of CDK7 and CDK9, as well as other components of the kinase complexes, MAT-1/cyclin H are upregulated during Human cytomegalovirus infection. In addition, there is an increase in the kinase activities of CDK7 and CDK9 (Tamrakar et al., Journal of Virology, 2005, 79; 15477-15493).

Many antiviral drugs target viral proteins. These have the disadvantage that viruses often develop resistance against these drugs. Antiviral drugs targeting cellular proteins essential for viral process, like CDK7, could bypass this disadvantage. These drugs may further be effective in treating several unrelated viruses and their effects should be additive to traditional antiviral agents. Inhibitors of CDK7, which has its dual function of CDK-activating kinase and transcription regulation is very effective in the treatment of several viruses.

It is object of the present invention to provide compounds and/or pharmaceutically acceptable salts thereof which can be used as pharmaceutically active agents, especially for prophylaxis and or treatment of cell proliferative diseases, inflammatory diseases, immunological diseases, cardiovascular diseases and infectious diseases, as well as compositions comprising at least one of those compounds and/or pharmaceutically acceptable salts thereof as pharmaceutically active ingredients.

This object is solved by the compounds and/or their pharmaceutically acceptable salts according to independent claim 1, the compounds of the present invention for use as pharmaceutically active agents, the use of the compounds of the present invention for the preparation of a pharmaceutical composition for the prophylaxis and/or treatment of infectious diseases, including opportunistic diseases, immunological diseases, autoimmune diseases, cardiovascular diseases, cell proliferative diseases, inflammation, erectile dysfunction and stroke according to independent claim 6, the use of compounds according to the present invention as inhibitors for the protein kinase CDK7.

If R¹¹ and R¹² are joined together, they form a ring system and especially a four-membered, five-membered or a six-membered ring system together with the atoms to which they are attached. Preferred ring systems are five-membered cyclocarbamates, five-membered cyclic ureas, five-membered cyclic guanidines, six-membered cyclocarbamates, six-membered cyclic ureas, six-membered cyclic guanidines, pyrrolidones, pyridones, piperidinones, imidazoles, imidazolines, pyrrolines, imidazolidin-2-ones.

R³ together with R⁴ can form a carbocyclic or heterocyclic 4-, 5-, 6- or 7-membered ring with the two carbon atoms of the benzo ring to which R³ and R⁴ are attached and that 4-, 5-, 6- or 7-membered ring can be partly saturated or unsaturated and can be substituted with 1 to 4 substituents selected from Z¹, Z², Z³ and Z⁴. Z¹ and Z² if attached to the same carbon atom can together represent ═O to form a carbonyl group with the carbon atom to which Z¹ and Z² are attached, so that so a ring has one carbonyl group and may comprise one or two further residues which are not allowed to form a carbonyl group together.

Partly saturated as used herein means that the ring system additionally formed by joining R³ with R⁴ when taken alone already bears one double bond originated in the phenyl ring to which R³ and R⁴ are attached. Thus, since R³ and R⁴ are attached to a phenyl ring a double bond equivalent exists between the two carbonatoms that bear R³ and R⁴, respectively. Therefore, the person skilled in the art will understand that the ring system formed when R³ and R⁴ are joined together can not be a saturated ring system, but a partly saturated ring system when the moiety introduces at least one saturated atom or two subsequent saturated bonds.

This is especially the case, if substituent R⁹ does not include the substituent R⁸.

R¹¹, R¹², R¹³, R¹⁴ and R¹⁵ represent independently of each other —H, linear or branched C₁-C₈-alkyl, C₃-C₈-cycloalkyl, C₁-C₉-heterocyclyl, linear or branched C₂-C₈-alkenyl, linear or branched C₂-C₈-alkynyl, C₆-C₁₄-aryl, C₁-C₁₀-heteroaryl, wherein the afore-mentioned residues can be substituted with 1 to 5 substituents selected from Z⁸, Z⁹, Z¹⁰, Z¹¹ and Z¹².

R¹¹, R¹², R¹³, R¹⁴ and R¹⁵ preferably represent independently of each other —H, methyl, isopropyl and pyrrolidinyl.

As used herein linear C₁-C₈-alkyl refers to —CH₃, —C₂H₅, —C₃H₇, —C₄H₉, —C₅H₁₁, —C₆H₁₃, —C₇H₁₅, —C₈H₁₇, —CH₂-Ph, —CH₂—CH₂-Ph, wherein these residues can be substituted with 1 to 5 substituents selected from Z⁸, Z⁹, Z¹⁰, Z¹¹ and Z¹². However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z⁸, Z⁹, Z¹⁰, Z¹¹ or Z¹². Moreover it is clear to a skilled person that only these hydrogen atoms which are present in the residue can be replaced by the substituents Z⁸, Z⁹, Z¹⁰, Z¹¹ and Z¹². Thus, since the methyl group has only three hydrogen atoms, only three hydrogen atoms can be replaced by three substituents selected from Z⁸, Z⁹, Z¹⁰, Z¹¹ and Z¹². For the definitions used herein the alkylaryl group —CH₂-Ph (benzyl group) and the —CH₂—CH₂-Ph group should fall under the definition “linear C₁-C₈-alkyl”.

The term “substituted” as used herein further indicates that the substituted residue like “substituted linear C₁-C₈-alkyl” does definitely have at least one substituent (at least one Z substituent) while the residue without the term “substituted” like “linear C₁-C₈-alkyl” can have at least one substituent. Consequently, if the term “substituted” is not used in relation to a residue this does not indicate that this residue is unsubstituted.

Examples of preferred substituted linear C₁-C₈-alkyl residues are —CH₂—OH, —CH₂—O—CH₃, —CH₂—OCF₃, —CF₃, —CH₂Cl, —CH₂CH₂Cl, —CH₂CH₂—OCF₃, and —CH₂-Ph.

However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z⁸, Z⁹, Z¹⁰, Z¹¹ or Z¹². The carbon atom number of C₁-C₈ refers only to the carbon atoms of the alkyl residue and does not include the carbon atoms of the substituents Z⁸ to Z¹².

Examples of preferred substituted branched C₁-C₈-alkyl or preferably branched C₃-C₈-alkyl residues are —CH(CH₂Cl)₂, —CH(CH₃)—C₂H₄—OCF₃, —C(CH₃)₂—CF₃, —COCH₃(CH₃)₂—, —CHCH₃Cl, —CH₂—CHCH₃NH₂, —CClCH₃—C₂H₅, —C(CH₃)₂OH, —CClCH₃—C₃H₇, —CH₂—C(OH)(CH₃)—C₂H₅, —CH(CH₃)—CHCH₃Cl, —C(CH₃)₂—C₂H₄NH₂, —CH₂—C(CH₃)₂O H, —CNH₂(C₂H₅)₂, —C₂H₄—COH(CH₃)₂, —C₃H₆—CON(CH₃)₂.

As defined above, the term “substituted” in “substituted branched C₃-C₈-alkyl” indicated that definitely at least one substituent is present while the term “branched C₃-C₈-alkyl” only defines that the carbon chain is branched but does not exclude further substituents. Consequently it is stated above that the “branched C₃-C₈-alkyl” residues can be substituted with 1 to 5 substituents selected from Z⁸, Z⁹, Z¹⁰, Z¹¹ and Z¹². Thus, for instance, the “substituted branched C₃-C₈-alkyl” residues are a subgroup of the “branched C₃-C₈-alkyl” residues. The same applies to the other residues which are mentioned with the term “substituted” and without the term “substituted”.

As used herein, C₃-C₈-cycloalkyl refers to cyclo-C₃H₅, cyclo-C₄H₇, cyclo-C₅H₉, cyclo-C₆H₁₁, cyclo-C₇H₁₃, and cyclo-C₈H₁₅, wherein these residues can be substituted with 1 to 5 substituents selected from Z⁸, Z⁹, Z¹⁰, Z¹¹ and Z¹². However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z⁸, Z⁹, Z¹⁰, Z¹¹ or Z¹². The carbon atom number of C₃-C₈ refers only to the carbon atoms of the cycloalkyl residue and does not include the carbon atoms of the substituents Z⁸ to Z¹².

Thus if R³ and R⁴ form together with the two carbon atoms of the phenyl group to which they are attached a fused ring system so that the moiety

represents a bicyclic moiety, the following ring fragments are preferred:

wherein the afore-mentioned 5-membered or 6-membered moieties or the afore-mentioned ring fragments consisting of 3 or 4 ring fragment atoms can be substituted with 1 to 4 substituents selected from Z¹, Z², Z³ and Z⁴. However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z¹, Z², Z³ or Z⁴. Moreover it is clear to a skilled person that only these hydrogen atoms which are present in the afore-mentioned carbocyclic or heterocyclic 4-, 5-, 6- or 7-membered rings or in the afore-mentioned ring fragments can be replaced by the substituents Z¹, Z², Z³ and Z⁴. Thus, since the ring fragment ═N—O—N═ does not have any hydrogen atoms, no substitution is possible at this 3 atom ring fragment.

Thus, it is preferred that the phenyl group together with R³ and R⁴ form the following bicyclic systems which can be further substituted with 1 to 4 substituents selected from Z¹, Z², Z³ and Z⁴ on the ring formed by R³ and R⁴ as well as with R⁵, R⁶ and R⁷ on the phenyl group which is the benzo group in the bicyclic ring:

The term “bridging carbocyclyl” refers to a carbocyclyl residue as disclosed herein, which is further bonded to a second substituent independent from any optional substitution with substituents Z¹, Z², Z³ or Z⁴. Thus, in a “bridging carbocyclyl” two hydrogen atoms are replaced by residues rendering the “bridging carbocyclyl” a di-yl moiety. Further, the “bridging carbocyclyl” binds the two different residues with two different carbon atoms, thereby preventing a substitution pattern wherein the two residues are bonded to the same carbon atom.

The term “bridging spirocarbocyclyl” refers to a spirocarbocyclyl residue as disclosed above, which is further bonded to a second substituent independent from any optional substitution with substituents Z¹, Z², Z³ or Z⁴. Thus, in a “bridging spirocarbocycly” two hydrogen atoms are replaced by residues rendering the “bridging spirocarbocyclyl” a di-yl moiety. Further, the “bridging spirocarbocyclyl” binds the two different residues with two different atoms of the spirocarbocyclyl skeleton, thereby preventing a substitution pattern wherein the two residues are bonded to the same atom.

However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z⁵, Z⁶ or Z⁷. It is also possible that two of the substituents Z⁵, Z⁶ and Z⁷ represent together an oxygen atom and form together with the carbon atom of the spiroheterocyclyl residue to which they are both attached a carbonyl moiety. Moreover, the C₅-C₁₄/N₀-N₂/O₀-O₂/S₀-S₁-spiroheterocyclyl residues are characterized by that the spiroheterocyclyl residue is linked through a carbon atom of the spiro ring system and not through the hetero atom, i.e. the nitrogen atom of the spiro ring system. If the spiroheterocyclyl residue contains a nitrogen atom which is substituted by one of the substituents Z⁵, Z⁶ and Z⁷, said Z substituent represents R¹². Thus the indication “N₁” refers to the group

of the spiro ring system. If the spiroheterocyclyl residue contains two nitrogen atoms which are both substituted by one of the substituents Z⁵, Z⁶ and Z⁷, the first Z substituent represents R¹¹ and the second Z substituent represents R¹². Thus the indication “N₂” refers to the groups

It is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z¹, Z², Z³ or Z⁴. Further, it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z¹, Z², Z³ or Z⁴. Moreover, it is clear to a skilled person that only these hydrogen atoms which are present in the “bridging spiroheterocyclyl” group can be replaced by the substituents Z¹, Z², Z³ and Z⁴.

The term “C₅-C₁₄/N₁-N₃” means that the spiro ring system consists of 5 to 14 carbon atoms and 1 to 3 nitrogen atoms. Moreover the spironitrogencyclyl residues can be substituted with 1 to 3 substituents selected from Z⁵, Z⁶ and Z⁷. However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z⁵, Z⁶ or Z⁷. It is also possible that two of the substituents Z⁵, Z⁶ and Z⁷ represent together an oxygen atom and form together with the carbon atom of the spironitrogencyclyl residue to which they are both attached a carbonyl moiety. Moreover the C₅-C₁₄/N₁-N₃-spironitrogencyclyl residues are characterized in that the spironitrogencyclyl residue is linked through a nitrogen atom of the spiro ring system and not through a carbon atom of the spiro ring system. This means in regard to the above-mentioned C₅-C₁₄-spiroheterocycly residue that the heteroatom Y is nitrogen and that this C₅-C₁₄-spiroheterocycly residue is linked to the rest of the molecule through this nitrogen atom (which is Y).

Moreover the nitrogenheterocyclyl residues can be substituted with 1 to 3 substituents selected from Z⁵, Z⁶ and Z⁷. However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z⁵, Z⁶ or Z⁷. It is also possible that two of the substituents Z⁵, Z⁶ and Z⁷ represent together an oxygen atom and form together with the carbon atom of the nitrogenheterocyclyl residue to which they are both attached a carbonyl moiety. Moreover the C₅-C₁₄/N₁-N₃/O₀-O₂/S₀-S₁-nitrogenheterocyclyl residues are characterized by that the nitrogenheterocyclyl residue is linked through a nitrogen atom of the spiro ring system and not through a carbon atom of the spiro ring system. This means in regard to the above-mentioned C₅-C₁₄-spiroheterocycly residue that the heteroatom Y is nitrogen and that this C₅-C₁₄-spiroheterocycly residue is linked to the rest of the molecule through this nitrogen atom (which is Y). If the C₅-C₁₄/N₁-N₃/O₀-O₂/S₀-S₁-nitrogenheterocyclyl residue contains a second nitrogen atom which is substituted by one of the substituents Z⁵, Z⁶ and Z⁷, said Z substituent represents R¹². Thus, the indication “N₂” refers to a first nitrogen atom through which the nitrogenheterocyclyl residue is linked and to the group

of the spiro ring system. If the nitrogenheterocyclyl residue contains a third nitrogen atom and both nitrogen atoms are substituted by one of the substituents Z⁵, Z⁶ and Z⁷, the first Z substituent on the second nitrogen atom represents R¹² and the second Z substituent on the third nitrogen atom represents R¹¹. Thus, the indication “N₃” refers to a first nitrogen atom through which the nitrogenheterocyclyl residue is linked and to the groups

of the spiro ring system. The indication “S₁” refers to the group —S— or —SO— or —SO₂— of the spiro ring system.

The indication “O₁” refers to the group —O— and the indication “O₂” to two groups —O— which are not directly linked to each other, while “O₀” indicates that no oxygen is present in the spiro ring system. Thus, the C₅-C₁₄/N₁-N₃/O₀-O₂/S₀-S₁-nitrogenheterocyclyl residue can contain in total 6 hetero atoms while in total not more than 3 hetero atoms should be present in the spiro ring system. Moreover it is preferred that the heteroatoms in the spiro ring system are not directly bond to each other.

Synthesis of Compounds

The inventive pyrazolo[1,5-a][1,3,5]triazines according to the present invention can be prepared by methods known to one skilled in the art. The synthesis is preferably carried out according to the general synthetic sequences, shown in schemes 3 and 4. This enables those skilled in the art to introduce to intermediate (IV) any suitable amine R²—NH₂ that is commercially available or can be synthesized according to or in analogy to literature procedures. Further, after introduction of a methylsulfoxide leaving group by oxidation of the thioatom in (V) compounds with this formed methylsulfoxide group provide the basis to react with many classes of C-, S-, N- or O-nucleophiles that are available either commercially or by synthetic means. Therefore, the synthetic approach according to schemes 3 and 4 enables the synthesis of any of the pyrazolo[1,5-a][1,3,5]triazines disclosed in the present invention. However a person skilled in the art can also prepare these compounds following to other synthetic sequences.

In the following schemes occurring abbreviations mean DCM (dichloromethane); DIPEA (N-ethyl-N,N-diisopropylamine); DMF (dimethylformamide); DMSO (dimethyl sulfoxide); EtOAc (ethyl acetate); EtOH (ethanol); mCPBA (3-chlorobenzoperoxoic acid); MeOH (methanol); MeCN (acetonitrile); TFA (trifluoroacetic acid), PhNEt₂ (dimethyl phenyl amine), Boc (tert-butyloxycarbonyl), Ph (phenyl), Ts (tosylate, p-toluenesulfonyl group), Mes (mesylate, methanesulfonyl group).

As depicted in scheme 1 in a first step 4-isopropyl-1H-pyrazol-5-amine was reacted with ethoxycarbonyl isothiocyanate to give a thiourea derivative that was cyclized to 2-mercaptopyrazolo[1,5-a][1,3,5]triazin-4-ol (II). The thiol (II) is then methylated by standard procedure to yield intermediate methylthioether (III).

Starting from (III) two further intermediate compounds can be derived as depicted in scheme 2. Firstly, after said methylation of the mercapto group in (II) 4-chloro-2-(methylthio)pyrazolo[1,5-a][1,3,5]triazine (IV) was obtained by chlorination of (III) with phosphoryl trichloride in the presence of N,N-diethylaniline. Secondly, by oxidation of (III) the sulfone derivative (XVII) can be synthesized. Both, intermediate (IV) and (XVII) can be used for synthesis of the compounds of the present invention of the general formula (I) via various synthetic routes.

The residue A¹ can be introduced by nuclephilic substitution reaction of (IV) with amines of the formula A¹NH₂, and DIPEA as a base yielding 4-amino-2-(methylthio)pyrazolo[1,5-a][1,3,5]triazines (V) as shown in scheme 3, wherein A¹ represents the upper benzyl building block of the compounds of the general formula (I)

wherein the R¹, R³ to R⁷ represent the residues as defined herein.

Compounds (V) were then oxidized with 3-chlorobenzoperoxoic acid to 4-amino-2-(methylsulfonyl)pyrazolo[1,5-a][1,3,5]triazines (VI) that could be substituted by reaction with compounds of the general formula R²—H yielding the compounds of the present invention of the general formula (I), wherein R² and A¹ represent residues as defined herein.

An alternative synthesis to the route outlined in scheme 3 is depicted in scheme 4 starting from intermediate (XVII). As one synthetic option the reaction of a nucleophile (R²—H) for introduction of the residue R² takes place before the incorporation of the amine A¹NH₂ (upper pathway). In addition as a second synthetic option it is possible to obtain chloride (XX) and subsequently substitute said chloride before the sulfone is replaced by R². The synthetic approach for the compounds of the general formula (I) according to scheme 4 has the advantage that the oxidation step for generating a sulfone from a thioether (here (III) converts to (XVII)) takes place before the introduction of the upper building block A¹ by reaction with the amine A¹NH₂. Accordingly, moieties A¹ being sensitive to oxidative reaction conditions can also be introduced, thereby broadening the scope of the compounds of the present invention significantly.

Conveniently, many ortho-substituted benzylamines A¹NH₂ as these are useful starting materials for the synthesis of the compounds of the general formula (I) are commercially available. Additional derivatives can be prepared by a person skilled in the art following known synthetic procedures that are disclosed in patent or non-patent literature.

In principle, following any approach for the preparation of the compounds with the general formula A¹-NH₂ and thereby for the compounds of the present invention with the general formula (I) two aspects have to be considered. Firstly, the generation of the benzylic amino group in A¹NH₂ and secondly, the introduction of the desired substitution pattern as represented by R³-R⁷.

Commonly used syntheses for said aminomethylphenyl derivatives are shown in scheme 5. Suitable starting materials include aryl halogenides, sulfonates, nitriles, oximes, halogenomethans and related precursors.

Depending on the target molecule with its specific substitution pattern (as represented by R³-R⁷) a person skilled in the art of organic chemistry will plan the synthetic approach for each benzylamine (XIII) individually and decide at which point the aminomethyl group and their related precursors will be synthesized. Also, scheme 5 shows merely exemplary synthetic methods for the preparation of compounds (XIII) which is only a specific embodiment of the moiety A¹, wherein R¹ is hydrogen. However, the person skilled in the art will understand that the below synthetic routes are also suitable for the preparation of amines A¹-NH₂ with any residue R¹ as defined herein.

According to the present invention ortho-substituent R³ in compounds of the general formula (I) is different from hydrogen. Starting from a wide range of commercially available materials many synthetic approaches can be applied to introduce the moieties at the respective position to yield compounds as defined in claim 1 and are well known to a person skilled in the art of synthesis.

For example, R³ in formula (I) can derive from a nucleophile. In such a case it can be introduced for example via reaction with a 2-fluorobenzonitrile derivative (XIV, scheme 6). Subsequently, ortho-substituted benzylamines (XVI) can be obtained by reduction of the corresponding nitrile (XV). Examples for nucleophiles represented by NuH are alcohols, amines, thiols or 5-membered heteroaromates such as pyrazole or triazole derivatives. If necessary, compounds of formula (XV) or (XVI) can be further modified in various positions before or after being used as building block (A¹-NH₂) according to schemes 3 and 4.

Other examples for aromatic substitutions of aryl halides, triflates or boronates are copper mediated Ullman-type or palladium catalyzed Buchwald-Hartwig reactions with N-, O- or S-nucleophiles.

Further, there is also a huge number of reactions that enable a person skilled in the art of organic chemistry attaching R³ in compounds of the general formula (I) via a carbon-carbon bond. These reactions include but are not limited to catalyzed (e.g. by palladium, nickel, copper or iron species) cross-coupling reactions of an appropriate aryl halides or sulfonate with an alkyl, aryl or heteroaryl boron-, zinc-, magnesium-, tin- or silicon-reagent. Alternatively, for introduction of the substituent R³ it is possible to transform an aryl halide or sulfonate (e.g. triflate) into one of the above mentioned metal species that can be used in a cross-coupling reaction with for example alkyl, aryl or heteroaryl halide R³—X. Further on scheme 3, synthetic options are presented for the rather general introduction of the residue R² in the following schemes 7-9:

For example intermediate (VI) can be reacted with different nucleophiles to give derivatives (VII)-(IX) that all bear different residues A² to A⁷ at the afore-mentioned R² position in (I) in scheme 3.

In one embodiment in the synthesis of the compounds of the present invention amides of formula (XII) were synthesized via introduction of a cyanide group, transforming the resulting nitriles into imidoesters (XI) which underwent a subsequent nucleophilic attack with primary or secondary amines A³A⁴NH and hydrolysis to yield said related amides (scheme 7).

For example, the autoimmune reaction is directed against the brain in multiple sclerosis and the gut in Crohn's disease. In other autoimmune diseases such as systemic lupus erythematosus (lupus), affected tissues and organs may vary among individuals with the same disease.

1. Measurement of Binding Affinities to CDKs

This protocol describes how the Lance Kinase Activity Assay was performed to determine IC₅₀ values of compounds of general formula (I) against CDK/Cyclin complexes. The principle behind this enzymatic assay is based upon the phosphorylation of the Ulight-Peptide Substrat. It is detected by using a specific EU-labeled anti-phospho peptide antibody. The binding of the Eu labeled anti-phospho peptide antibody to the phosphorylated ULight® labeled peptide gives rise to a FRET-signal.

Binding of an inhibitor to the kinase prevents phosphorylation of the Ulight-MBP Substrat, resulting in a loss of FRET.

The compounds of general formula (I) exemplary summarized in Table 1 were diluted from a 10 mM DMSO stock solution 1:10 in a total volume of 15 μl DMSO. This compound predilution was then serial diluted 1:3 over 8 steps in DMSO and briefly spun down. Each compound solution was now diluted 1:20 in Enzymatic Buffer (HEPES: 50 mM, pH: 7.5; MgCl₂: 10 mM; EGTA: 1 mM; DTT: 2 mM; Tween-20: 0.01%), mixed thoroughly and spun down.

For every sample, 2 μl of the diluted compound were mixed with 6 μl CDK2/CycA/substrate working solution (8.33 nM CDK2/CycA; 83.33 nM ULight MBP substrate in enzymatic buffer) and 2 μl ATP working solution (15 μM ATP in enzymatic buffer) in a well of a small volume 384 well plate (Corning Incorporated, Corning, N.Y., USA; order no. 3673). For negative controls, in each well 2 μl of DMSO working solution (5% DMSO diluted in enzymatic buffer) was mixed with 6 μl substrate working solution (83.33 nM ULightMBP substrate in enzymatic buffer) and 2 μl ATP working solution. For positive controls, 2 μl of DMSO working solution were mixed with 6 μl CDK2/CycA/substrate working solution and 2 μl ATP working solution. Positive and negative controls were calculated from at least 8 different wells. The 384 well plates were mixed in a Teleshaker plate mixer (Beckman Coulter, Brea, Calif., USA) at 2000 rpm for 40 sec, and incubated for 1 h at room temperature before addition of 10 μl LANCE Detection Buffer (EDTA: 20 nM; Eu-Anti-P-MBP: 4 nM) per well. Plates were mixed in a Teleshaker plate mixer (Beckman Coulter, Brea, Calif., USA) at 2000 rpm for 40 sec, followed by incubation with Detection Buffer for 1 h, and reading. The FRET signal was measured at 340 nm excitation, 665 nm and 615 nm emission (for the ULight MBP substrate and LanthaScreen Eu-AB, respectively) with an Envision spectrophotometer (Perkin Elmer, Waltham, Mass., USA) with 90 μs delay and 20 μs integration time. IC₅₀ values were determined from the sigmoidal dose response curves with the software Quattro Workflow (Quattro GmbH, Munich, Germany). In case of tight binding of the inhibitors to CDK2/CycA, final assay concentrations were adjusted to 0.25 nM Eu-Anti-MBP AB, 2 nM CDK2/CycA and 30 μM ATP, and IC₅₀ values were converted according to the Cheng Prusoff equation to the IC₅₀ values at the original ATP-concentration.

The compounds of general formula (I) exemplary summarized in Table 1 were diluted from a 10 mM DMSO stock solution 1:10 in a total volume of 15 μl DMSO. This compound predilution was then serial diluted 1:3 over 8 steps in DMSO and briefly spun down. Each compound solution was now diluted 1:20 in Enzymatic Buffer (HEPES: 50 mM, pH: 7.5; MgCl₂: 10 mM; EGTA: 1 mM; DTT: 2 mM; Tween-20: 0.01%), mixed thoroughly and spun down.

For every sample, 2 μl of the diluted compound were mixed with 6 μl CDK7/CycH/Mat1/substrate working solution (16.66 nM CDK7/CycH/Mat1; 83.33 nM ULight MBP substrate in enzymatic buffer) and 2 μl ATP working solution (125 μM ATP in enzymatic buffer) in a well of a small volume 384 well plate (Corning Incorporated, Corning, N.Y., USA; order no. 3673). For negative controls, in each well 2 μl of DMSO working solution (5% DMSO diluted in enzymatic buffer) was mixed with 6 μl substrate working solution (83.33 nM ULightMBP substrate in enzymatic buffer) and 2 μl ATP working solution. For positive controls, 2 μl of DMSO working solution were mixed with 6 μl CDK7/CycH/Mat1/substrate working solution and 2 μl ATP working solution. Positive and negative controls were calculated from at least 8 different wells. The 384 well plates were mixed in a Teleshaker plate mixer (Beckman Coulter, Brea, Calif., USA) at 2000 rpm for 40 sec, and incubated for 1 h at room temperature before addition of 10 μl LANCE Detection Buffer (1×; EDTA: 20 nM; Eu-Anti-P-MBP: 4 nM) per well. Plates were mixed in a Teleshaker plate mixer (Beckman Coulter, Brea, Calif., USA) at 2000 rpm for 40 sec, followed by incubation with Detection Buffer for 1 h, and reading. The FRET signal was measured at 340 nm excitation, 665 nm and 615 nm emission (for the ULight MBP substrate and LanthaScreen Eu-AB, respectively) with an Envision spectrophotometer (Perkin Elmer, Waltham, Mass., USA) with 90 μs delay and 20 μs integration time. IC₅₀ values were determined from the sigmoidal dose response curves with the software Quattro Workflow (Quattro GmbH, Munich, Germany). In case of tight binding of the inhibitors to CDK7/CycH/Mat1, final assay concentrations were adjusted to 2 nM Eu-Anti-MBP AB, 10 nM CDK7/CycH/Mat1 and 250 μM ATP; or 2 nM Eu-Anti-MBP AB, 3 nM CDK7/CycH/Mat1 and 2500 μM ATP, and IC₅₀ values were converted according to the Cheng Prusoff equation to the IC₅₀ values at the original ATP-concentration.

Comparative Examples

In order to show the surprising effects of the compounds of the present invention the Comparative Examples C-I and C-II, wherein according to the compounds of the general formula (I) R³═H, have been tested in the enzymatic activity assays for CDK2, CDK7 and CDK9 as described above.

C-I and C-II have the following structural formulae:

The selectivity results of Comparable Examples C-I and C-II are directly comparable to the compounds of the present invention as summarized in Table 5. While all compounds show potency against CDK-7, only the compounds of the present invention do not significantly inhibit also CDK-2 and CDK-9. Therefore, the compounds of the present invention can selectively inhibit CDK-7. The degree of selectivity is demonstrated in Table 6 by the multiplicity of the CDK2 and CDK9 activity in terms of the CDK7 activity. For example, while C-I only shows a 9-fold CDK7 activity for CDK2 and a 14-fold CDK7 activity for CDK9 indicating that C-I rather inhibits all three CDK inhibitors, the compounds of the present invention selectively inhibit only CDK7 while the activities for CDK2 and CDK 9 are tremendously higher (up to over the 9000-fold activity of the CDK7 activity).

Also, members of the CDK family have been validated as targets in cancer and inflammatory disease as well as in HIV-1 treatment. However, first generation CDK-inhibitors (Flavopiridol, Roscovitine, SNS-032) do typically inhibit more than one member of the CDK family. Such non specific-CDK inhibitors are meanwhile known for their toxicities and small therapeutic windows in clinical trials. Indeed, knockdown of multiple CDKs is lethal in a variety of model organisms, whereas knockdown of single CDKs is frequently tolerated; indicating that inhibition of single CDKs is less toxic.

Therefore, the main goal in the field of CDK-inhibition is the optimization for selective small-molecule based CDK-inhibitors.

As becomes apparent from Table 7 below first generation CDK-inhibitors generally do not show satisfactory CDK7 inhibition in comparison to the compounds of the present invention, nor do they show any significant effect that CDK 2 or CDK 9 are not inhibited simultaneously. This could at best be addressed for BS-181, however the comparative CDK 7 inhibition is poor and the CDK 2 and CDK 9 inhibition is far below a hundred-fold activity of the CDK 7 activity. In case of SNS-032 and Flavopiridol the CDK 2 and CDK 9 activities are even lower than the CDK 7 activity.
